From c011b6f67e909cffe6496bc07d3359b5b74b1d63 Mon Sep 17 00:00:00 2001 From: Subv Date: Fri, 8 Jun 2018 17:05:52 -0500 Subject: GPU: Synchronize the blend state on every draw call. Only independent blending on render target 0 is implemented for now. This fixes the elongated squids in Splatoon 2's boot screen. --- src/video_core/renderer_opengl/gl_rasterizer.cpp | 26 ++++++++++++++++-------- 1 file changed, 18 insertions(+), 8 deletions(-) (limited to 'src/video_core/renderer_opengl/gl_rasterizer.cpp') diff --git a/src/video_core/renderer_opengl/gl_rasterizer.cpp b/src/video_core/renderer_opengl/gl_rasterizer.cpp index 6bc0dbd38..6f05f24a0 100644 --- a/src/video_core/renderer_opengl/gl_rasterizer.cpp +++ b/src/video_core/renderer_opengl/gl_rasterizer.cpp @@ -349,6 +349,9 @@ void RasterizerOpenGL::DrawArrays() { // Sync the viewport SyncViewport(surfaces_rect, res_scale); + // Sync the blend state registers + SyncBlendState(); + // TODO(bunnei): Sync framebuffer_scale uniform here // TODO(bunnei): Sync scissorbox uniform(s) here @@ -735,14 +738,21 @@ void RasterizerOpenGL::SyncDepthOffset() { UNREACHABLE(); } -void RasterizerOpenGL::SyncBlendEnabled() { - UNREACHABLE(); -} +void RasterizerOpenGL::SyncBlendState() { + const auto& regs = Core::System().GetInstance().GPU().Maxwell3D().regs; + ASSERT_MSG(regs.independent_blend_enable == 1, "Only independent blending is implemented"); -void RasterizerOpenGL::SyncBlendFuncs() { - UNREACHABLE(); -} + // TODO(Subv): Support more than just render target 0. + state.blend.enabled = regs.blend.enable[0] != 0; -void RasterizerOpenGL::SyncBlendColor() { - UNREACHABLE(); + if (!state.blend.enabled) + return; + + ASSERT_MSG(!regs.independent_blend[0].separate_alpha, "Unimplemented"); + state.blend.rgb_equation = MaxwellToGL::BlendEquation(regs.independent_blend[0].equation_rgb); + state.blend.src_rgb_func = MaxwellToGL::BlendFunc(regs.independent_blend[0].factor_source_rgb); + state.blend.dst_rgb_func = MaxwellToGL::BlendFunc(regs.independent_blend[0].factor_dest_rgb); + state.blend.a_equation = MaxwellToGL::BlendEquation(regs.independent_blend[0].equation_a); + state.blend.src_a_func = MaxwellToGL::BlendFunc(regs.independent_blend[0].factor_source_a); + state.blend.dst_a_func = MaxwellToGL::BlendFunc(regs.independent_blend[0].factor_dest_a); } -- cgit v1.2.3
